What is “improved” about HD radio?
Because the signal is digital, it can carry more on the broadcast band, offering CD-like quality, including full bandwidth bass and excellent treble, better dynamic range, and is immune to multipath interference. HD radio can also carry data information to be displayed on the radio receiver and multicast programming (such as 102.3-1 and 102.3-2). When KHNS completes its upgrade, these services will be offered as well.
